Rochester M6300 Liquid Level Transmitter

Rochester M6300 Liquid Level Transmitter is a two‑wire, 4‑20 mA transmitter designed to work with Rochester’s Magnetel 6300 Rough Rider mobile liquid‑level gauges, converting float position into a loop current for remote monitoring. In LP gas service, the M6300‑LP version pairs with the R6315‑12 transmitter to provide a two‑wire 4‑20 mA signal that scales from 4 mA at 0% fill to 20 mA at 100% fill, enabling precise readings of propane or other LP tanks in transport and mobile installations. The Magnetel Rough Rider line is explicitly described as rugged for mobile service, built to withstand vibration and shock, and the mobile installation is addressed in TPED‑certified guidelines; the 6300 series is positioned to indicate liquid level as a percentage of tank volume, offering a compact, robust solution for continuous level measurement in demanding environments. By combining the gauge’s magnetic level sensing with the transmitter's current output, this setup supports common industrial controllers and remote displays without complex wiring, suitable for propane, other liquefied gases, and similar liquids in mobile storage applications.
